| Abstract: | The biological characteristics and the techniques of introduction and cultivation in the field of 24 cultivars of Tulipa gesneriand was studied. The results showed that they could grow normally and didn' t degenerate on sandy loam. The period of growth was about 200 days. Maximum single bulb weighed 76 gram , increasing 24 gram. The new bulb weighed 34.6 graias in average, incressing 2. 8 grams. The rates of reproduction of flowering bulb and steall buld were 4 and 2-3 respectively. The flower bud differentiated normally when the bulb was stored in the well-ventilated room with a moderate temperature of 20-30? and relative humidity of 68-94% from June to August. |
